Abstract

La présente invention concerne une aiguille de transfusion veineuse anti-acupuncture jetable, comprenant une base d'aiguille (1), un manchon d'aiguille (4), un tuyau flexible (3) et une tête d'aiguille (41), où la tête d'aiguille est emboîtée (41) avec le manchon d'aiguille (4) et le tuyau flexible (3) est en communication avec la base de l'aiguille (1). L'aiguille de transfusion veineuse comprend également un manche (11), une partie coulissante (2) et un mécanisme de limitation. La base d'aiguille (1) est tubulaire, et une extrémité de la base d'aiguille (1) fixe et est raccordée à la tête d'aiguille (41), et l'autre extrémité est raccordée au tuyau flexible (3). La partie coulissante (2) est tubulaire avec deux extrémités ouvertes, et possède une section rectangulaire. Le manche (11) est disposé sur la base de l'aiguille (1) à l'extrémité à proximité de la tête d'aiguille (41). Un côté de la partie coulissante (2) est pourvu d'une rainure de piste (22) dans la direction axiale de la partie coulissante (2), le manche (11) traverse et est fixé de façon coulissante dans la rainure de piste (22), et la longueur de la rainure de piste (22) est supérieure à celle de la tête d'aiguille (41). Le mécanisme de limitation est disposé sur la partie coulissante (2), la base d'aiguille (1) et/ou le manche (11). La partie coulissante (2) est pourvue de façon annulaire d'une protubérance lisse (21). Par réglage de la partie coulissante (2) de telle sorte qu'elle puisse coulisser sur la base d'aiguille (1) pour protéger la tête d'aiguille (41), la sécurité de manipulation de la tête d'aiguille (41) post-transfusion est fortement augmentée, et en évitant l'utilisation d'une tête d'aiguille chargée par ressort, la souffrance du patient est réduite.
